A Mobile Ad hoc NETwork (MANET) is a self-organized system comprised of mobile wireless nodes with peer relationships. Due to multi-hop routing and absence of any trusted third party in open environment, MANETs are vulnerable to attacks by malicious nodes. In order to decrease the hazards from malicious nodes, we introduce the concept of trust to MANETs and(More)
Hardware implementation of human detection is a challenging task for embedded designs. This paper presents a real-time image-based field-programmable gate array (FPGA) implementation of human detection. Our implementation is based on the histograms of oriented gradients (HOG) feature and linear support vector machine (SVM) classifier. The novelty of this(More)
The effect of acidification and heat treatment of raw red mud (RM) and fly ash (FA) on the sorption of phosphate was studied in parallel experiments. The result shows that a higher efficiency of phosphate removal was acquired by the activated samples than by the raw ones. The sample prepared by using the RM stirred with 0.25 M HCl for 2h (RM0.25), as well(More)
As a kind of typical embedded system, MANET is a multi-hop self-configuring network with the topology changes dynamically. To model of the security, mobility, and dynamic changes of MANET, trust is used as a novel concept recently. In this paper, based on the classic fuzzy theory, the trust evaluation and the dynamic routing protocols for MANET are(More)
Mobile ad hoc networks are originally designed for the environment that is cooperative and in which every node has constrained resources such as energy and communication radius. In virulent environments, compared with traditional methods, trust-based routing protocol could bring better service quality. In this study, considering the black-hole attack and(More)
The as-grown CNTs and graphitized CNTs were used as adsorbents to remove 1,2-dichlorobenzene from water. The experiments demonstrate that it takes only 40 min for CNTs to attain equilibrium and the adsorption capacity of asgrown and graphitized CNTs is 30.8 and 28.7 mg/g, respectively, from a 20 mg/l solution. CNTs can be used as adsorbents in a wide pH(More)
A mobile ad hoc network (MANET) is a self-organized system comprised by multiple mobile wireless nodes. Due to the openness in network topology and the absence of centralized administration in management, MANET is vulnerable to attacks from malicious nodes. In order to reduce the hazards from these malicious nodes, we incorporate the concept of trust into(More)
